20 Most Recent 1995 GMC Sierra C1500 Questions & Answers


You didn't say what engine size, but no matter for me. That sounds like the ignition control module-about the size of a matchbook, and 4 or 5 wires to it. GM often put them in the base of the distributor.
The PCM controls spark timing by signaling to the ignition control module. This module controls the ignition coil, it cuts the primary current to the coil (when the pcm signals it), so that high voltage spark is generated from the coil.

It may not be the alternator causing the vibration - it could be something else being driven by that belt. I would take off the belt and check the idler pulley first, then the rest to see if there is a misaligned pulley or one of them is very rough or loose when being manually turned.

Found these two fuses for hvac. Use a test light, check voltage on fuse circuit, key on. Yes, the ignition switch is involved. Check feed to ignition switch, both show to be red wires, hot all the time. The feed from ignition switch to hvac shows to be orange wire.

ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
12900_oil_sending_unit_and_fuel_pump_circuit_80-yoo05im5qhid2i2poe1uh03c-5-0.gif this is for the fuel system, relay for the injector is nearly the same.

It probably smokes all the time , when moving you don't notice it > What color smoke ? White - coolant is getting in to the combustion camber , head gasket , intake manifold . Blue - oil is being burnt - rings , valve seals , Black - running rich , leaking fuel injectors . leaking fuel pressure regulator . Smokes from were , exhaust ? Engine bay etc....

Have you had any issues with your oil level raising? You could have an injector sticking open slightly letting the residual fuel pressure that is in the line bleed fuel into the engine after shutting the engine off.

there are several sensors including the VSS, TCM, vacuum actuator oil pressure and ECM
the idea is to read the fault codes to show the problem units
